First, purchase Black Plastic Hardware Cloth from Home Depot or Lowes.Â Roll it out and cut to the size you think would appropriate for your display.Â Next, push 12mm pixels through the holes to align a
grid pattern.Â We put three holes in each direction which is about two inch spacing.Â To make it wider than the roll, overlap to extend it to the correct width.Â After you've finished, align the pattern to the sequencer of your choice and see the results.
